13e it known that 1","FRDfKIEK, a citi'- Z-en of the United States, anda resident of Mount Vernon, in the county of Westchester and State ofNew York, have inventeda new and Improved Insulatffr'` forfHigh-,VoltageElectric-Cable Spliclesi, of whichthe following is a. full, clear,y andexacty'descriptionf. This invention relates to electric conductors, andhas particular reference to providing yan insulated couplingorsplicingmea'ns for'high voltage electric cablesfwhich iso'f'a morereliable and satisfactoryfjnature than those heretofore usually'relie'd' upon.I` i

Among the objects of the invention more definitely stated is to providelai' couplingfor multiple cable conductors. in which there 'is yprovided a core which'is inserted between aoA of the core. j

the several' strands or cables, said core being of a' solid nature o rone which provides the maximum surface spacel from one cable to thenext. i

A further object of the invention isito providea coveringincludingvja'sleeve made in one part or a plurality of partslongitudinally arranged and-having interlocking com nections Awith theseveral cables and parts The foregoing and'other obj ects of theinvention will hereinafter be more fully described and claimed andillustrated in the drawings forming apart of this specification in whichlike characters of reference indicate corresponding parts in all theviews, andin whichdf-1 n Figure 1 is a longitudinal'sectional view of adevice made accordance with .this invention, certain `parts being inelevation, the sectional part being on the line-f-m of Fig. 2; Fig. 2'is a vertical 'transverse section on the line y-f-y .of Fig; 1;- andFig. 3

-is a transverse sectionof a slight modification.

The severalv parts of the device may be made of any suitable materials,and the relan tive sizes and proportions, as well as the general designof the mechanism, may be varied to a considerable extent withoutdeparting from the spirit of the invention hereinafter more fully setforth and lspecifically claimed.

Referring more particularly to the drawings for a better understanding-of the invention, l show a plurality of cables or high voltageconductors 10 shown herein as three in number, but as to tlie number ldo not 'wish to be limited as a greater or less 'numy Specificatie? 0fLetter` Patent.

ber'inight bey used. r"endsiof a. cable to'bespliced,"indicated atlO,may be' protecting one cable from the'n`eX't."f*-f At 13 Ik show a corerkof anylsuitable composition or insulatingmaterial, said 'core havinga.solid centerand of generallycylindrical configuration but providedfwithpockets or grooves M for the receptioniof-the individual cables ]oinedas' :above described that 1s to say, each of the grooves )Avis adaptedto receive snugly a single complete "cable, the cable coming well withinthe outer boundary ofthe corelflt will be'noted, therefore,that

the' free gap' from one cable to the-,next isof'f considerable "distance.followingfthe outer surface of the core. .f

Surrounding the corel and inclosing or embracing the cables associatedtherewith is a vsleeve 15 adapted to be lslipped longitudif n'allyalong' and intolinterlocking engagement with'the core, there lbeingprovided for the purpose 'of such interlock a plurality of tongues 16each having a concave surface receiving-the outer surface of one h andprojecting on oppositesi'des ofthecable into the groove 14. Thetongzgues,-therefore prevent any possibility of circumferential movementof the sleeve aroundI the. axis lof lthe core. The sleeve may be incasedin a1. sheath 18 having its ends wipedat 18 in connection with'the usualleadcovering 19 for the several cables.

In order to increase the free surface gap between 'onecable and the nextatthe core I,

provide a plurality ofv4 grooves 20, extending longitudinally of andparallel tothegrooves 14, each groovevQO being preferablymidway of eachtwo adjacent grooves .14. For electricity, therefore, to pass from l thenext along the surface ofl the core, it will be required -to travel aLvery long distance the curved portions ofthe core and the three wallsof the groove 20.

In the herein described coupling device for high voltagemultiple electric cables, the combination of a solid core of insulatingmaterial having a plurality of longitudinal grooves extending from oneend to the other into which the several cables aforesaid are adapted tolie in spaced relation to one another, and a sleeveitted to the exteriorsurface of the core and having as many pairs of tonguesfintegral'with;the sleeve as there are grooves aforesaid inthe core, each pair ofltongues projecting into a core groove and embracing the outer surface4of the cable therein. 1

2. The herein described coupling device for high voltage multipleelectric cables, comprising a rigid core of ,insulating material`havinga plurality of grooves extending along the same from one end to theother and adapted to receive the several cables therein in spacedrelation, said core also being provided with longitudinal groovesarranged along the surface thereof between the first mentioned grooves,and -a multi-part sleeve fitted to 'the outside of the core, each I partof the sleeve having means projecting into one of the first mentionedgrooves to embrace the cable therein and also having a palr of marginalradially projecting flanges extending intov the grooves of the lattermen` tionedy group on each side of the cable groove, substantially asset forth.

ln testimony whereof I have signed'my' name to this specification in tWosubscrlbing witnesses.
